Kinetic of Growth Processes of PbTe:Bi Nanocrystalline Structures on Mica-Muscovite Cleavages Substrate
Journal Title: Фізика і хімія твердого тіла - Year 2015, Vol 16, Issue 2
Abstract
The results of investigation of formation plumbum telluride epitaxial films by atomic force microscopy are presented. The surface topology of PbTe films grown by hot wall method on micas-muscovite fresh cleavages substrates for 350 - 630 K condensation temperatures range and thickness up to 10 μm are given. This indicated the presence of the vapour - crystal growth processes of a films without a coalescence.
Crystal-Chemical Interpretation of Amphoteric Influence of Bismuth Impurity in Tin Telluride
Models of point defects of doped by bismuth tin telluride crystals considering amphoteric influence of dopant ( ) have been specified. The influence of disproportionation of charge state of impurity on the conductivity t...

Electroinduced Diffusion of Lithium Ions into the Structure of Magnesium Fluoride
It has been established that in the process of intercalation/deintercalation of lithium ions into the MgF2-based cathode material, thediffusion coefficient is (1-3) 10-12sm2/s during intercalation and (0,6-3) 10-11sm2/s...
